Review: Best monitor I’ve used - The 480 hz 1440p oled is really good for its price, there is so many points I want to make though. In gaming it’s 480hz obviously but I think it’s better than 540hz TN or IPS panels because the oled panel makes it more natural and there is WAYY less ghosting than the other panels I’ve come across. The other point I wanted to make is that you need a really powerful gpu to run it without stuttering which is ideally something equivalent to an RTX 5080 which I use with a ryzen 7 9800x3d and also 32gb ddr5 ram. I don’t know if this is with all oled panels but sometimes I do get flickering and I did my research and found out that it is VRR (variable refresh rate) which causes the flickering. Now my monitor doesn’t do that I’m guessing this because I turned off hardware acceleration and instantly it stopped flickering. Also the way this monitor works is really good in games like valorant or Fortnite and even Black ops 6 because i play 2560x1440 on low-medium settings with DLSS on gets me about 500-570fps. The monitors stand I’m a really big fan of because it does not take too much space which is a good thing about this monitor. As a £750 monitor (I bought it for £650) it is still really reasonable for its price and because I’m a very competitive gamer this is truly the best monitor I have ever played on. I moved from 360hz TN panel to this. This monitor is also good for content creators or people that edit pictures or videos which really gives you the colour accuracy since oled is the most natural panel and it’s best known for colour accuracy at the end of the day. One thing I wouldn’t advise is if you want this monitor for office work or just typing emails and stuff then I would recommend a different monitor since this monitor is mostly for gamers and people that have things to do with content creation or just creation in general. This monitor also has oled image cleaning which basically prevents your panel from getting burn in. Also please if you have read this long review put a fully black wallpaper in windows and also auto hide your taskbar to prevent burn-in. Thanks so much for reading this and if you buy this monitor, enjoy it to the fullest
Review: A great, responsive OLED, but update the firmware and settings - I chose this LG UltraGear as my new main monitor, specifically opting for a WOLED panel over a QD-OLED. My desk is next to a large window, so I wanted a monitor with a matte screen that could handle reflections well for both work during the day and gaming at night, and this has been the perfect choice for that scenario. Coming from what was a fairly high-end IPS display when it released, the leap to OLED is staggering. It is a huge improvement in every single regard: the colours are significantly richer, the inky blacks are truly perfect, and the responsiveness is on another level. For gaming, this monitor is simply impressive. The incredible refresh rate makes competitive games feel exceptionally fluid, while the perfect contrast ratio is a game-changer for darker, atmospheric horror games. The experience extends to media, too. Watching HDR Blu-rays on this display is a treat; the visuals are so impressive that they even surpass my main TV. The inclusion of DisplayPort 2.1 is also a great touch for future-proofing. However, it's important to address the software. Many of the reported launch issues, like the poor 60Hz responsiveness, have been fixed via firmware updates and hopefully more improvements will come in the future. The update process is easy enough, though the PC application you use feels clunky and has some poor translations. More importantly, I would strongly recommend new owners dive into the settings immediately. The default picture mode has an adaptive brightness that can make the screen unreadably dim at random moments. Switching to a different mode and making a few tweaks makes a world of difference.

### ⭐⭐⭐⭐⭐ Downgraded from 32" to 27" - Best Decision I Made
*by A***R on 7 November 2025*

I switched from last year's 32GS95UV (32" 3rd gen WOLED) to this 27" QHD model. The 32" was overwhelming on my 120x60cm desk - both the size and resolution caused eye strain. My previous 27" 4K IPS had similar issues, but when LG released their 4th gen WOLED in this size first, I decided to try it. It's exceeded my expectations completely. HDR on Mac actually works: Using HDMI 2.1, both Windows and Mac display perfectly calibrated HDR out of the box. I could never get proper HDR on the 32GS95UV with MacOS - this worked immediately. (Note: Use HDMI, not DisplayPort, for proper calibration.) Brightness is finally sufficient: You're not sacrificing brightness anymore. At maximum it's almost too bright. Combined with the subtle matte anti-glare coating, I can comfortably use this facing a window. QHD is the right balance: Yes, you lose some sharpness versus 4K, but the improved sub-pixel layout keeps text usable. After being burned by 4K panels that looked sharper but caused headaches, I'll take slightly softer text that I can actually use for extended periods. This display works for both Mac work and Windows gaming without fatigue - genuinely life-changing. Overall improvements: Perfect blacks, 280Hz, and noticeably better color calibration than 3rd gen panels. LG has finally closed the gap with Apple's displays. Can't wait to see what else they release with this 4th gen technology. Note: confusingly LG has another variant of this called 27GX790 which is an older 3rd gen panel - avoid that one. This review is for the 27GX700 - the first 4th gen panel. Worth upgrading to!
